A randomized comparison of a rapid versus prolonged (24 hr) infusion of cisplatin in therapy of squamous cell carcinoma of the uterine cervix: A gynecologic oncology group study

In this study, 331 patients with advanced or recurrent squamous cell carcinoma of the cervix no longer amenable to control with surgery or radiotherapy were randomized to receive cisplatin 50 mg/m² as either a continuous infusion over 24 hr or a more rapid infusion at a rate of 1 mg/min. Antiemetic therapy was standardized for the initial course of both regimens as metoclopramide 60 mg at the time of and at 3 and 6 hours after initiation of cisplatin. The overall frequency of objective regression of disease was 18%; the response rate in each regimen was essentially identical. The continuous infusion regimen was associated with a significantly greater percentage of patients who experienced no nausea and vomiting (34% versus 18%, P = 0.002). Other adverse effects included nephrotoxicity, peripheral neuropathy, myelosuppression, and ototoxicity. Both the frequency and severity of these were essentially the same for each regimen.
